Just to give some more product feedback to our OP on his initial question.
I dug out my Chase Volante 2023 version. I originally bought it as it had a low middle. Very similar to
@jonny77 middle position 17.5cm (3 inches) from toe. Or as I like to call it ‘a ball width’.
I think we would all agree a good bat pings perfectly well enough a ball width from the toe, and a ball width under splice/stickers.
I am very happy with my volante and surprised how elongated the middle is on the bat considering it’s a low middle profile.
I’ve measured a Salix AJK and a Salix Pod. Both start to peak more like 4 inches from toe. Very much mid/middle looking profiles.
But performance wise, ping starts a ball width from toe, and a ball width below splice/stickers. The pod even has the spine running into the toe. But it’s very much dead in the toe area and is more of a duckbill toe finish.
So 3 different profile bats. All with varying middle positions. But perform exactly the same in the same areas.
I’d also like to mention that the volante is 2,8. And the pod is 2,10.
The Pod feels lighter and more balanced.
The other thing I have to remind myself when browsing at bats, is that in 3 seasons time that bat will be absolutely pinging everywhere from being so well played in. Bats take time and patience to reach performance not necessarily profile shape.
